My heater was blowing cold air. So we back flushed the radiator and put new in antifreeze and it worked when we test drove it. Then I went on a longer drive and it worked for the first minute or less and then blew cold air after that. Yesterday when I drove it I got back in after driving a long distance and for the first minute or less it was hot air that turned cold. I have a 2001 Jeep Grand Cherokee V8.

Why would my 2002 Jeep Grand Cherokee only blow luke-warm to cold air when the fan is on high? First the heat went on the highest setting, so i used the second highest.

I have a 2002 Jeep Grand Cherokee Limited with the automatic climate control option. Within the last few weeks, I have noticed cold air seeping under the passenger side dashboard, near the blower mechanism. It seems that the faster you drive, the more air comes in.
